Corrosion Principles and Control Technology

• Introduction.
• Fundamentals of corrosion.
• Corrosion types.
• Corrosion forms.
• Corrosion control by design improving:

–  Simplifying the forms. –  Avoiding the residual moisture. –  Avoiding the galvanic corrosion.

• Corrosion control by change of metal:

–  Change of composition. –  Change of structure. –  Change of stress condition.

• Corrosion control by change in the corrosive medium :

–  Removal of corrosive constituents. –  Addition of corrosion retarding substances.

• Corrosion control by change of the electrode potential :

–  Cathodic protection. –  Anodic protection.
